2 The nickname of the Chicago team was the "Black Hawks" for the majority of the streak – 17 of the 28 seasons. They were renamed the "Blackhawks" in 1986.

3 The Montreal Canadiens only missed the playoffs once - by a tie-breaker - in the 46 seasons from 1948–49 to 1993–94. In the 1969–70 season, they tied for fourth and last playoff spot with the New York Rangers, but were eliminated on total goals scored tiebreak (they scored 244 goals to New York's 246).

5 The Edmonton Oilers streak is the longest run from the NHL debut of a franchise, starting from the first year they were in the NHL (1979–80); although they aren't included in the NHL streak, they also made the WHA playoffs the preceding 4 seasons (1975–76 through 1978–79), for a streak of 17 consecutive playoff appearances in major professional hockey.
